![]() This relates to some extent to the lack of independence between roles in production optimisation and technical responsibility for well integrity. The latest audit found verification and documentation of integrity status to be lacking for a number of production and injection wells. When the PSA audited Okea’s maintenance management on Draugen in 2019, it found that the company faced challenges in establishing and updating its own management system with associated processes and procedures. Neither Okea nor other licensees in the production licence have subsequently considered an internal or independent review and verification of well integrity status, despite the field’s long producing life and associated lengthy production and injection history. Several have long had weaknesses without Okea conducting an internal verification of well integrity status since taking over as operator.Īn internal assessment of the wells at the transfer from Shell was carried out by Okea personnel who did not participate in the audit. Resultsĭraugen has a number of wells with deficient or weakened barriers today, without plans having been presented for repairing or restoring them. The PSA wanted to verify the company’s follow-up of the technical condition of the platform and subsea wells on Draugen, with monitoring and maintenance of well integrity, and that planned well maintenance is being carried out in a robust manner. That includes processes for risk management, well maintenance and following up the integrity of the Draugen wells. The purpose of the audit was to assess how Okea ensures compliance with official regulations and its own internal requirements related to major accident risk and hydrocarbon leaks. The field is produced with the aid of pressure support through water injection and the use of gas lift in certain wells. These are about 1 600 metres deep and homogenous, with good reservoir properties. Oil is produced on Draugen from two formations. The operator is expected to apply for an extension to the field’s producing life. It came on stream in 1993.ĭraugen’s original producing life was 30 years, and Okea currently has consent to stay on stream until 2024. The field has been developed with a concrete gravity base structure supporting an integrated topsides, and features both platform and subsea wells. Norske Shell (Shell) was the operator for Draugen until December 2018, when this responsibility was taken over by Okea. ![]() ![]() Its licensees are Okea (operator), Petoro and Neptune Energy. Backgroundĭraugen lies in the Norwegian Sea. The audit was carried out on 9-10 September 2020. The order was issued on 17 November 2020. Notice of the order was given on 28 October 2020.
